A disc brake assembly for a bicycle, comprising: a master housing defining a master chamber having a first end and a second end, said master housing adapted to be mounted on a fork of said bicycle; a reservoir housing defining a reservoir chamber having a first end and a second end; a compensating body mounted within said reservoir chamber, said compensating body and said reservoir chamber cooperating to form a compensating chamber; a compensating biasing member distal said compensating body from said second end of said reservoir chamber, said compensating biasing member biasing said compensating body toward said second end of said reservoir chamber; a first compensating channel defining a first compensating flow path connecting said master chamber and said compensating chamber; a master piston shaft, said master piston shaft mounted at least partially within said master chamber; a master piston mounted on said master piston shaft defining a primary chamber between said master piston and said first end of said master chamber; a seal between said master piston shaft and said master housing, said seal at least partially defining a secondary chamber between said master piston and said second end of said master chamber; a brake piston housing defining a brake piston chamber; a brake channel defining a brake flow path connecting said primary chamber with said brake piston chamber; a brake piston reciprocally mounted within said brake piston chamber, wherein said master piston shaft is movable from a braking position wherein said first flow path is in communication with said secondary chamber and a release position wherein said first flow path is in communication with said primary chamber.
